A smaller number in front of a larger number means subtraction, all else means addition. For example, IV means 4, VI means 6.You would not put more than one smaller number in front of a larger number to subtract. For example, IIV would not mean 3. You must separate ones, tens, hundreds, and thousands as separate items. That means that 99 is XCIX, 90 + 9, but never should be written as IC. Similarly, 999 cannot be IM and 1999 cannot be MIM.
